Subarus do weird things with aftermarket intakes. What brand was it?

SPT... but the thread makes me think that drop at 3900 is what everyone else sees too. I'm pretty sure I've got the same thing, which is why I looked for a dyno sheet in the first place.

On a side note, those numbers are high because that's a DynoJet. But if you're making comparisons, it sounds like STIs are making similar numbers on his dyno so that's pretty impressive.

I remember hearing about similar problems with the newer STI limited factory ECU programming... I was talking to a guy at a meet who had one and he was mentioning similar woes.

Wow it looks like they are really running it lean to help spool up and then run it rich once it hits boost. Looks like the turbo is running out of air up top which is why it is falling off. Common fixes are better exhaust/intake/cams, but youll still have the same problem till a bigger turbo.

i think subaru also does that with the AF to control emissions to an extent since the N/A's have an almost identical AF curve (hits the "rich" part at 4500 as opposed to 4000)

They supposedly just released tuning for the SI-Drive system but the info on the site referenced doesn't even talk any technical specifications.

Yea i'm thinking the A/F change at 4kish is the OL/CL transition. That's odd though I would think it would kick out of cloosed loop a lot sooner than 4k though especially at WOT. I looked mine up in Enginuity and mine switches from OL to CL at ~70% throttle below 3600.
